Margaery arrives in King's Landing. At her wedding to Joffrey her betrothed chokes to death on the poison known as the Strangler. Tyrion Lannister is accused of the murder, when in actual fact the culprits were Petyr and Olenna.

Margaery attends the wake of Lord Tywin Lannister along with the rest of her family. Her and her cousins talk and laugh with Tommen afterwards. Her grandmother promises Cersei Lannister that they will talk about a date for the wedding. She later attends the prayers that take place in the Great Sept of Baelor whilst Tywin's corpse rots.
